:description: Instructions for setting up switches that send out pre-defined sequences of IR or RF signals
|

:keywords: Infrared, IR, RF, Remote, TX
|
|
|
|
|
|
The ``remote_transmitter`` component lets you send digital packets to control
|
|
devices in your home. For example this includes infrared data or 433MHz RF signals.
|
|
|
|
First, you need to setup a global hub that specifies which pin your remote
|
|
sender is connected to. Then you can use the available actions to send encoded
|
|
remote signals.
|
|
|
|
**See** :ref:`remote-setting-up-infrared` **and** :ref:`remote-setting-up-rf` **for set up guides.**
|
|
|
|
.. note::
|
|
|
|
This component is more accurate on the ESP32, since that chipset has a dedicated
|
|
peripheral for sending exact signal sequences.

Configuration variables:

|
------------------------
|
|
|
|
- **pin** (**Required**, :ref:`config-pin`): The pin to transmit the remote signal on.
|
|
- **carrier_duty_percent** (*Optional*, int): How much of the time the remote is on. For example, infrared
|
|
protocols modulate the signal using a carrier signal. Set this is ``50%`` if you're working with IR leds and to
|
|
``100%`` if working with a other things like 433MHz transmitters.
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify
|
|
the ID used for code generation. Use this if you have multiple remote transmitters.

Remote Transmitter Actions
|
|
--------------------------
|
|
|
|
Remote transmitters support a number of :ref:`actions <config-action>` that can be used
|
|
to send remote codes. All supported protocols are listed below. All actions additionally
|
|
have these configuration variables:
|
|
|
|
.. code-block::yaml
|
|
|
|
on_...:
|
|
- remote_transmitter.transmit_x:
|
|
# ...
|
|
repeat:
|
|
times: 5
|
|
wait_time: 10ms
|
|
|
|
Configuration variables:
|
|
|
|
- **repeat** (*Optional*): Optionally set the code to be repeated a number of times.
|
|
Defaults to sending the code only once.
|
|
|
|
- **times** (int): The number of times to repeat the code.
|
|
- **wait_time** (:ref:`config-time`): The time to wait between repeats.
|
|
|
|
- **transmitter_id** (*Optional*, :ref:`config-id`): The remote transmitter to send the
|
|
remote code with. Defaults to the first one defined in the configuration.
|

|
Setting up Infrared Devices
|
|
---------------------------
|
|
|
|
In this guide an infrared device will be set up with ESPHome. First, the remote code
|
|
will be captured with an IR receiver module (like `this one <https://www.sparkfun.com/products/10266>`__).
|
|
We will use ESPHome's dumping ability to output the decoded remote code directly.
|
|
|
|
Then we will set up a new remote transmitter with an infrared LED (like
|
|
`this one <https://learn.sparkfun.com/tutorials/ir-communication/all>`__) to transmit the
|
|
code when a switch is triggered.
|
|
|
|
First, connect the infrared receiver module to a pin on your board and set up a
|
|
remote_receiver instance:
|
|
|
|
.. code-block:: yaml
|
|
|
|
remote_receiver:
|
|
pin: D0
|
|
dump: all
|
|
|
|
Compile and upload the code. While viewing the log output from the ESP,
|
|
press a button on an infrared remote you want to capture (one at a time).
|
|
|
|
You should see log output like below:
|
|
|
|
.. code-block:: text
|
|
|
|
# If the codec is known:
|
|
[D][remote.panasonic] Received Panasonic: address=0x4004 command=0x8140DFA2
|
|
|
|
# Or raw output if it's not known yet
|
|
# The values may fluctuate a bit, but as long as they're similar it's ok
|
|
[D][remote.raw] Received Raw: 4088, -1542, 1019, -510, 513, -1019, 510, -509, 511, -510, 1020,
|
|
[D][remote.raw] -1020, 1022, -1019, 510, -509, 511, -510, 511, -509, 511, -510,
|
|
[D][remote.raw] 1020, -1019, 510, -511, 1020, -510, 512, -508, 510, -1020, 1022
|
|
|
|
If the codec is already implemented in ESPHome, you will see the decoded value directly -
|
|
otherwise you will see the raw data dump (which you can use just as well). You have
|
|
just successfully captured your first infrared code.
|
|
|
|
Now let's use this information to emulate a button press from the ESP. First, wire up the
|
|
IR diode to a new pin on the ESP and configure a global ``remote_transmitter`` instance:
|
|
|
|
.. code-block:: yaml
|
|
|
|
remote_transmitter:
|
|
pin: D1
|
|
# Infrared remotes use a 50% carrier signal
|
|
carrier_duty_percent: 50%
|
|
|
|
This will allow us to send any data we want via the IR LED. To replicate the codes we decoded
|
|
earlier, create a new template switch that sends the infrared code when triggered:
|
|
|
|
.. code-block:: yaml
|
|
|
|
switch:
|
|
- platform: template
|
|
name: Panasonic Power Button
|
|
turn_on_action:
|
|
- remote_transmitter.transmit_panasonic:
|
|
address: 0x4004
|
|
command: 0x8140DFA2
|
|
|
|
# Or for raw code
|
|
switch:
|
|
- platform: template
|
|
name: Raw Code Power Button
|
|
turn_on_action:
|
|
- remote_transmitter.transmit_raw:
|
|
code: [4088, -1542, 1019, -510, 513, -1019, 510, -509, 511, -510, 1020,
|
|
-1020, 1022, -1019, 510, -509, 511, -510, 511, -509, 511, -510,
|
|
1020, -1019, 510, -511, 1020, -510, 512, -508, 510, -1020, 1022]
|
|
|
|
Recompile again, when you power up the device the next time you will see a new switch
|
|
in the frontend. Click on it and you should see the remote signal being transmitted. Done!

|
Setting Up RF Devices
|
|
---------------------
|
|
|
|
The ``remote_transmitter`` and ``remote_receiver`` components can also be used to send
|
|
and receive 433MHz RF signals. This guide will discuss setting up a 433MHz receiver to
|
|
capture a device's remote codes. After that we will set up a 433MHz transmitter to replicate
|
|
the remote code with the press of a switch in the frontend.
|
|
|
|
First, connect the RF module to a pin on the ESP and set up a remote_receiver instance:
|
|
|
|
.. code-block:: yaml
|
|
|
|
remote_receiver:
|
|
pin: D0
|
|
dump: all
|
|
# Settings to optimize recognition of RF devices
|
|
tolerance: 50%
|
|
filter: 250us
|
|
idle: 4ms
|
|
buffer_size: 2kb
|
|
|
|
Compile and upload the code. While viewing the log output from the ESP,
|
|
press a button on an RF remote you want to capture (one at a time).
|
|
|
|
You should see log output like below:
|
|
|
|
.. code-block:: text
|
|
|
|
# If the codec is known:
|
|
[D][remote.rc_switch] Received RCSwitch: protocol=2 data='100010000000000010111110'

# The values may fluctuate a bit, but as long as they're similar it's ok

|
.. note::
|
|
|
|
If the log output is flooded with "Received Raw" messages, you can also disable raw
|
|
remote code reporting and rely on rc_switch to decode the values.
|
|
|
|
.. code-block:: yaml
|
|
|
|
remote_receiver:
|
|
pin: D0
|
|
dump:
|
|
- rc_switch
|
|
tolerance: 50%
|
|
filter: 250us
|
|
idle: 4ms
|
|
buffer_size: 2kb
|
|
|
|
If the codec is already implemented in ESPHome, you will see the decoded value directly -
|
|
otherwise you will see the raw data dump (which you can use just as well). You have
|
|
just successfully captured your first RF code.
|
|
|
|
Now let's use this information to emulate a button press from the ESP. First, wire up the
|
|
RF transmitter to a new pin on the ESP and configure a global ``remote_transmitter`` instance:
|
|
|
|
.. code-block:: yaml
|
|
|
|
remote_transmitter:
|
|
pin: D1
|
|
# RF uses a 100% carrier signal
|
|
carrier_duty_percent: 100%
|
|
|
|
This will allow us to send any data we want via the RF transmitter. To replicate the codes we decoded
|
|
earlier, create a new template switch that sends the RF code when triggered:
|
|
|
|
.. code-block:: yaml
|
|
|
|
switch:
|
|
- platform: template
|
|
name: RF Power Button
|
|
turn_on_action:
|
|
- remote_transmitter.transmit_rc_switch_raw:
|
|
code: '100010000000000010111110'
|
|
protocol: 2
|
|
|
|
# Or for raw code
|
|
switch:
|
|
- platform: template
|
|
name: Raw Code Power Button
|
|
turn_on_action:
|
|
- remote_transmitter.transmit_raw:
|
|
code: [4088, -1542, 1019, -510, 513, -1019, 510, -509, 511, -510, 1020,
|
|
-1020, 1022, -1019, 510, -509, 511, -510, 511, -509, 511, -510,
|
|
1020, -1019, 510, -511, 1020, -510, 512, -508, 510, -1020, 1022]
|
|
|
|
Recompile again, when you power up the device the next time you will see a new switch
|
|
in the frontend. Click on it and you should see the remote signal being transmitted. Done!
